What does %* mean in a batch file?

Question

I have seen the usage of %* in batch files and command lines.

Can someone explain the typical usage of %* with an example?

Answer 1

It means "all the parameters in the command line".

For example, it's useful when you want to forward the command line from your batch file to another program:

REM mybatchfile.cmd
echo You called this with arguments: %*
echo I will now forward these to the DIR command.
dir %*
